下面是通過讀取xml文件中的內容并顯示在textbox的例子：

using System;
using System.Data;
using System.Configuration;
using System.Web;
using System.Web.Security;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Web.UI.WebControls.WebParts;
using System.Web.UI.HtmlControls;
using System.Xml;
using System.Xml.XPath;

public partial class _Default : System.Web.UI.Page
{
??? public string[] x = new string[4];
??? protected void Page_Load(object sender, EventArgs e)
??? {

??????? XmlDocument xmlDoc = new XmlDocument();
??????? xmlDoc.Load(Server.MapPath("table.xml"));//你的xml文件
??????? XmlNodeList xmlList = xmlDoc.SelectSingleNode("MapSheet").ChildNodes;
??????? foreach (XmlNode xmlNo in xmlList)
??????? {
??????????? //XmlNodeList xe = (XmlNodeList)xmlNo;
??????????? XmlElement xe = (XmlElement)xmlNo;
??????????? {
??????????????? if (xe.Name == "TableName")
??????????????? {
??????????????????? y[0] = xe.InnerText;
??????????????? }

??????????????? if (xe.Name == "DataSource")
??????????????? {
??????????????????? y[1] = xe.InnerText;
??????????????? }

??????????????? if (xe.Name == "UserName")
??????????????? {
??????????????????? y[2] = xe.InnerText;
??????????????? }

??????????????? if (xe.Name == "Password")
??????????????? {
??????????????????? y[3] = xe.InnerText;
??????????????? }
??????????? }
??????? }
??????? TextBox1.Text=y[0];
??????? TextBox2.Text = y[1];
??????? TextBox3.Text = y[2];
??????? TextBox4.Text = y[3];
??? }

}該程序已經過測試，沒有問題。
